Many other methods are professional, you can refer to the following yourself.
I. Software products
1, set virtual memory.
There is a very large data exchange file in the hard disk, which is reserved by the system for temporary storage in virtual memory. Many applications are often used, so the system needs to access a large amount of data to main memory frequently, so the speed of accessing this file constitutes a very important factor affecting the speed of the computer! Generally, the default of Windows is that the virtual memory is managed by the system itself, and the size of the swap file will be automatically adjusted according to the needs of different programs, but such enlargement and reduction will bring extra burden to the system and slow down the operation of the system! In view of this, it is best for users to customize the minimum and maximum values of virtual memory to avoid frequent size changes. To set up virtual memory, right-click My Computer and select Properties. In the advanced options of the Efficiency dialog box, set the virtual memory.
2, completely delete the program
As we all know, if you want to delete some programs, you can do it in Add/Remove Programs, but do you know that it will only help you delete programs, but it will not help you delete registration codes and some login items? To completely delete the program, find some "professional" software to delete! Nortonuninstall produced by Symantec has stopped selling all over the world because some parts damaged the copyright of some deleted software, which is why Symantec produced cleansweep. But functionally speaking, nortonuninstall has a longer life! Anyway, in fact, in addition to these two softwares, there are many similar softwares that can effectively delete programs.
3. Check the application software or drivers.
Some programs will slow down the computer system when they are started. If this is the reason, you can start with "safe mode". Because this is the initial startup, Safe Mode is slower than normal operation. However, if you start in "safe mode", you find that the computer starts faster than normal, which may be the reason why a program causes the system to start slowly.
4. Too many desktop icons will bring trouble.
Too many desktop icons will also slow down the system startup. Every time Windows starts and displays the desktop, it needs to find the icons of desktop shortcuts one by one and load them. The more icons, the more time it takes. At the same time, some anti-virus software provides system startup scanning function, which will consume a lot of time. In fact, if you have turned on the real-time monitoring function of antivirus software, the scanning system will be a bit redundant when starting, so it is better to disable this function! I suggest that you put the uncommon desktop icons in a special folder or simply delete them!
5. Due to ADSL, the system starts slowly.
By default, Windows XP will self-check network devices such as network cards at startup. If the IP address of the network card is found to be incorrectly configured, it will be set, which may be the real reason for the slow system startup. At this time, we can open the "Local Area Connection" property menu, and double-click "Internet Protocol" in the "General" item to open the "TCP/IP Properties" menu. Configure the IP address of the network card to a value that has not been used by the public network (the default gateway is 192. 168. 1), such as192.1. X, where x is a value between 2 and 255.
6. The influence of font on speed
Although Microsoft claims that Windows operating system can install 1000 ~ 1500 fonts, in fact, when you install more than 500 fonts, there will be problems, such as: fonts disappear from the font list of application programs, and the startup speed of Windows drops sharply. It is suggested to delete unused or commonly used fonts. In order to avoid accidents after deletion, you can make necessary backups first.
7. Delete the random startup program
What is a random boot program? A random boot program is a program that is loaded at boot time. Random startup program will not only slow down the startup speed, but also consume computer resources and memory faster. Generally speaking, if you want to delete random startup programs, you can delete them in the startup list, but if you want to be more detailed, such as QQ, popkiller and other software, you can't delete them in the startup list. You should go to accessory applications, system tools, and then. Press Tools in the toolbar above, and then press System Configuration Editor. After entering, in the "startup" dialog box, the random startup program loaded when starting the computer will be listed in detail! XP system, or you can enter Msconfig in "Run" and call "System Configuration Utility" to terminate the system random startup program. 2000 system needs to copy msconfig program from XP.
8. Cancel the background and close activedesktop.
I don't know if you have noticed that the beautiful background we have been putting on the desktop is actually a waste of computer resources! Not only that, it will also slow down the computer when executing applications! I wanted to beautify the desktop, but it slowed down the computer, so we didn't need the background. To do this, right-click the desktop, click Content, and then select None in the Background dialog box. In the Appearance dialog box, the preset turquoise on the desktop turns black ... As for closing activedesktop, you will be told to close the web screen from the desktop. So don't turn it on if the system configuration is not high.
9. Upgrading Kingsoft Internet Security can also slow down the system.
If you upgrade Kingsoft Internet Security and find that the system speed is very slow and the utilization rate of PU is always high, then this problem may be caused by the upgrade file of Kingsoft Internet Security. If a friend encounters this situation after upgrading, please do the following: First, enter the installation directory of Kingsoft Internet Security and find the file KAExtend. DAT, then delete it, and then click Tools/Online Upgrade of Kingsoft Internet Security to update the file KAExtend. DAT online, finally restart the computer to solve.
10, making Windows slimmer.
Compared with DOS system, Windows is too big, and with your daily operation, install new software, load runtime, add new games and so on. It becomes bigger, and more importantly, it is not only its directory, but also its registry and runtime. Because even if a program is deleted, the DLL file it uses will still exist. Therefore, with the long-term use, the DLL files that need to be loaded when Windows starts and exits are getting bigger and bigger, and the running speed of the natural system is getting slower and slower. At this time, you need to use some programs that completely delete dll, which can make Windows slim again. It is recommended that the best players reinstall Windows once every two months, which is very effective.
1 1, change the system startup time.
Although you already know how to add and delete some random startup programs, do you know what the computer is doing from booting to entering Windows? Or, what program is being executed? These programs must be fully loaded before entering Windows. Have you ever thought that if you can delete some unnecessary startup programs, the startup speed will be accelerated? The answer is yes! If you want to modify, you can press "Start", select "Execute", and then enter win.ini. After opening, you can delete the contents of the following paragraphs, even the titles! They include: [Compatibility], [Compatibility 32], [ime Compatibility], [Compatibility 95], [Module Compatibility] and [Embedding].
Second, hardware.
1, the Windows system automatically turns off the hard disk DMA mode.
Everyone should know the DMA mode of hard disk. PATA modes of hard disk are DMA33, DMA66, DMA 100, DMA 133, and the latest SATA- 150 has come out! Generally speaking, most people still use the hard disk in PATA mode, and the transmission speed of the hard disk in DMA mode is 2~8 times faster than that in PIO mode. DMA mode plays an important role in system performance. But you know what? Windows 2000, XP and 2003 systems sometimes turn off the DMA mode of the hard disk and automatically switch to PIO mode! This leads to the sudden decline of hard disk performance when using the above system, and the most obvious phenomenon is that the startup speed of the system is obviously slow. Generally speaking, when a normal Windows XP system starts, the slider moving from left to right can start the system up to 2 ~ 4 times, but when this problem occurs, it may go 5 ~ 8 times or even more! Moreover, the hard disk operation is obviously slow when the system is running. When running some large-scale software, the CPU utilization often reaches 100%, which leads to a pause, while when playing some large-scale 3D games, the picture obviously stops. When the above problems occur, you'd better see if the DMA mode of your hard disk is automatically turned off by the Windows system. Check whether your system is turned on in DMA mode:
A. Double-click management tools, and then double-click computer management;
B. Click System Tools, and then click Device Manager.
C. expand the node "IDE ATA/ATAPI controller";
D. double-click your "main IDE controller"; E. click advanced settings.
When you see Device 0, the following transfer mode should be set to DMA (if available) and then set to Current Transfer Mode. If it is "super DMA mode * (* is a number, DMA33 is 2, DMA66 is 4, DMA 100 is 5, DMA 133 is 6)", then your system is normal. But if you set Super DMA Mode 6 before and didn't change it, now it's Super DMA Mode 4 or Super DMA Mode 2 or PIO Mode and you can't change it! Maybe the system turned off DMA mode by itself.
2. Whether the 2.CPU and fan work normally and whether there is enough refrigeration.
When the speed of the CPU fan slows down, the temperature of the CPU itself will rise. In order to protect the security of CPU, CPU will automatically reduce the running frequency, which will slow down the running speed of the computer. There are two ways to detect the temperature of the CPU. You can use the "finger test" method to test whether the temperature of the processor is hot, but it should be noted that this method must first unplug the power plug and then connect a ground wire to prevent static electricity from penetrating the CPU or even damaging the CPU. Another scientific method is to use a multimeter with a temperature sensor to detect the temperature of the processor.
Because the types and models of processors are different, the reasonable temperature is also different. But generally speaking, the temperature should be lower than 1 10 degrees. If the processor test is found to be higher than this temperature, check whether the fan in the chassis works normally.
3, the impact of USB and scanner
Since Windows tests every drive (including the optical drive) at startup, if a CD is placed in the optical drive, it will also extend the startup time of the computer. So if the computer is equipped with scanners and other devices, or the USB hard disk is connected when it is started, then try to disconnect them first to see if the startup speed has changed. Generally speaking, due to the slow speed of USB interface, the corresponding devices will obviously affect the startup speed of the computer, so you should try to connect USB devices after startup. If there is no USB device, it is recommended to turn off the USB function directly in BIOS settings.
4. Do you use disk compression?
Because "disk compression" may cause a sharp decline in computer performance, resulting in a slower system speed. So at this time, you should check whether "disk compression" is used. The specific operation is to click the right mouse button on "My Computer" and select the "Properties" option from the pop-up menu to view the properties of the drive.
5, the influence of the network card
As long as it is not set properly, the network card will obviously affect the startup speed of the system. If your computer is connected to the local area network, after installing the network card driver, the system will automatically get the IP address through DHCP by default, but most companies' local area networks do not have DHCP servers. Therefore, if the user is set to "automatically obtain the IP address", the system will constantly search for DHCP servers in the network at startup until it obtains the IP address or times out, which will naturally affect the startup time. Therefore, LAN users had better specify a fixed IP address for their computers.
6. Folders and printers * * *
Computers with Windows XP Professional Edition will also start very slowly. Sometimes, the system seems to give people the feeling of collapse. After logging into the system, the desktop does not appear, and the computer seems to stop responding. It will take 1 minute before it can be used normally. This is because after using the Bootvis.exe program, the Mrxsmb.dll file adds 67 seconds to the computer startup!
To solve this problem, just stop * * * sharing folders and printers: select Start → Settings → Network and Dial-up Connections, right-click Local Area Connection, select Properties, uncheck the check box before * * * sharing files and printers on Microsoft network in the open window, and restart the computer.
7. Improper configuration of system accessories
Some users often ignore some trivial matters when assembling machines, which leads to improper matching of computer accessories and speed bottlenecks. For example, some friends choose high-end CPU, but sound cards and the like all buy ordinary cheap goods. In fact, this is often not worth the loss. Because in this way, when the computer is running games and playing DVD, the sound card occupies high CPU resources, the data transmission speed is slow, or there is no hardware decoding at all, and software decoding is needed, which often leads to the pause of sound and even the intermittent operation of programs. For example, some friends have upgraded their machines. Some parts of the old machine, such as memory chips, are unwilling to be abandoned and installed on the new machine. However, due to the speed limitation of the old memory, new machines often have to slow down to adapt to it, thus reducing the performance of the whole machine and greatly affecting the overall running speed.
8. Hardware drivers
Many players are novices. They don't know much about hardware drivers. When installing Windows, they don't know how to install drivers. It's like cooking jiaozi in a teapot. Can not pour out, can not give full play to the performance of hardware, a great waste of resources. As we all know, the same hardware, different versions of drivers or drivers from different manufacturers often lead to huge differences in performance, not to mention no drivers. Take playing DVD as an example. Even if you are the most advanced TNT graphics card, if there is no driver installed, you will not use the acceleration function of any graphics card when playing DVD, but use software to simulate the acceleration, and the effect is naturally terrible.
9. Disconnect unused network drives.
In order to eliminate or reduce the number of network connections that Windows must re-establish, it is suggested to disconnect some unnecessary network drives, that is, go to My Computer, right-click the mapped network drive and select Disconnect.
10, out of memory.
One advantage of Windows operating system is multi-line and multi-task. The system can use CPU for time-sharing operation, so that you can do many things at the same time. But there are advantages and disadvantages, and multitasking will also put forward higher requirements for your machine. Friends all know that even the most commonly used WORD software needs about 16MB of memory, but when running large-scale software such as 3D MAX, 64MB of memory is not enough. So at this time, the system will automatically use the hard disk space in virtual main memory to run programs and store exchange files and various temporary files. Because hard disk is a mechanical structure and memory is an electronic structure, the speed difference between them is several orders of magnitude, so virtualizing main memory with hard disk will greatly slow down the running speed of the program.
1 1, hard disk space is insufficient.
One disadvantage of using Windows system platform is unclear file management. Sometimes you don't know whether this file is useful to the system at all, so there are more and more files in the Windows directory, and the capacity is getting bigger and bigger. In addition, the current software likes more and more, and some temporary files and swap files generated by the system will make the available space of the hard disk smaller. When the available space of hard disk is less than a certain extent, it will cause the system to lack the available space for exchange files and temporary files, which will reduce the operating efficiency of the system. More importantly, because we frequently store and delete all kinds of software on the hard disk, the available space of the hard disk becomes fragmented, so the system often does not store files in a continuous order, which will lead to the frequent movement of the head when the system stores and reads files, greatly reducing the running speed of the system.
